'FAuce-r.

SPECIFICATION forming part of Letters Patent No. 255,881, dated April 4, 1862.

' Y Applicatidn filed January 12, 1882. (No model.) l

To all whom it may concern:

. Be it known that I, DAVID MORRISON, a citizen of the United States, residing in the city ot' New York, county of New York, and State of New York,`have invented certain new and useful Improvements in Faucets, fullydescribed and represented in the following specication and the accompanyingdrawings, forming a part of the same.

This invention relates to that class of faucets or cocks by which water or other liquid or tluid received from either of two sources of supply is delivered through the same. nozzle, or vice versa, and which are known inthe art as three-way faucets or cocks. Some of its features, however, may be applied with equal advantage to faucets of other constructions.

It is the object of this invention to produce a faucet or cock which shall be more satisfactory in its `operation and which will be less liable to become leaky in use than those herctofore produced; and to that end the invention consists in certain details of construction and combinations of parts, all oi" which are hereinafter too fully explained and pointed out to make an extended preliminary description necessary.

In said drawings, Figure `1 is a side elevation of a three-way cock embodying my invention; Fig. 2, a transverse vertical sectlon upon the line .fr fc of Fig. l; Fig. 3, a horizontal section upon the lineyyof Figs. 2 anti 4. Fig. 4is

aplan view, partly in section, lot a compoundl three-way cock embodying the invention; Fig. 5, a side elevation, also partly in section, of the cock shown in Fig. 4, the plugs, however, being in a different position; and Fig. 6, a perspective View of the plug.

rlhe casing or shell 10 ot' the cock is provided with two lateral projections, 40 4l, both of which are provided with screw-threads, so as to aord a means for readily attaching the pipes leading from the two sources of supply. These projections are provided with longitudinal passages 11 l2, which open into the vertical passage 13, containing the plug 14.

The opening 13 and the plug 14, which tits it accurately, are of the usual shape, being cy lindrical and slightly tapered toward their lower ends. A

Into the lower end' of the plug 14 extends the duct 15, into which opens the port 16, which is so located that as the plug is turned it will register with the openings 11 and l2. (See Figs. 2 and 3.)

Surrounding the lower end of the plug 14 is t the annular projection 42, w hich is also screwthreaded, and to which is secured the pipe 30.

4This pipe may be in the form of anpelbow, asy shown in Fig. 1, and carry at its end the nozat this time closed by the solid wall of t-he plug 14. IF, however, the plug be given a haltturn, which can be readily done by the handle 18,

`secured to its projecting upper end, 9, the operation will be reversed, opening l2 will` be closed, and port 16 will be brought into register with opening 11, so that water will be drawn from the other source of supply, while that from the first is entirelyy cut oit'. When it is desired to cut oft both supply-pipes the plug is given a quarter-turn from the position shown in Figs. 2 and 3, which brings the ports in such position that both openings 11 and 12 are closed by the solid walls ot' the plug.

Cocks constructed upon this plan will be found very convenient in connection with washbowls, bathtubs, sinks, Src., when both hot and cold water are used.

The upper end of the plug 14 is cut away so as to form upon it the shoulderland 2, and terminates in the spindle 17, to which thelever 1S is attached in any convenient manner. As shown in the present case, the lever 18 is made in the form otl a key or wrench, which tits onto the square portion 9 of the spindle, being held in place by the set-screw 43. The plug is c onstantly forced downward and held firmly in its seat in the shell or casing of the cock by the spring-washer 3, contained in an annular chamber formed between the plug andthe upward projection 44 ot' the shell 10, and resting upon the shoulder 1. This spring 3 is con loo fined and pressed against the shoulder l by the cap 19, which screws onto the projection 44.

The cap 19 is provided with the upwardlyprojecting :liange 20, between which and the stern 17 there is (owing to the latter being cut away to form the shoulder 2)ananuularcha1n ber, which is filled with a packing, 45, of any suitable Inateriahf' This packing is confined in the chamber by the cap 21, which screws onto the flange 20.

In faucets or cocks of this class as coinmonly constructed the accuracy with which the plug tits into its seat is the only provision againstleakage. Experience,however,proves that this is not sufficient, and that it is difficult, ifnot impossible, to construct a cock upon this plan which will in use remain perfectly water-tight'.- for any considerable length of time. The packing cures this defect and prevents the'possibility ot' the cock leaking upon its upper side.

With the construction shown the packing 45, when worn, can be readily renewed without the necessity ot' removing the plug and consequently of cutting the water ott from the building. This is done by loosening set-screw 43, removing lever 18, and then unscrewing and removing cap 2l.

To prevent leakage through the joint between the lower end ot' the plug and the eX- tension 42 ot' the shell, the packing 4 is provided. This packing rests upon a shoulder formed on the pipe 30, and is of sufficient width to cover both the ends of projection 42 and the shell ot' plug 14. This packing likewise can be renewed by unscrewing pipe 30 without cutting oft' the water in the service-pipes.

It is evident that a cock constructed upon this plan may receive water from three or Veven more different sources of supply and deliver itl through the same nozzle, it being only necessary to provide the shell with a corresponding number of project-ions, as 40 41, and openings, as 11 and 12.

Cocks of this construction are also well adapted for use in regulating the flow of'liquids and uids generally, as well as of water;A and it is also evident that b v reversing the direction of the tlow ofthe liquid or iiuid through the cock they may be used to draw the substance from a single source of supply into either of two or more receptacles or eductionpipes.

In Figs. 4 and 5 this invention is shown as applied to a compound three-way cock, which consists of two three-way cocks so mounted with relation to each other that their plugs can be simultaneously operated by a single lever or handle. these compound cocks, being well known in the art, need no specie description. In these figures is shown a slight modification in the devices for holding the packing 45 in place. The annular chamber formed between the spindle 17 and flange 20 of cap 19, instead of being open at its top and provided with a cap, 21, for holding the packing in place, is closed at its top by an inward projection upon iange 20, which tits tightly around spindle 17. To insert the packing 45, the cap 19 is uuserewed from projection 44 and the packing inserted from the side next the shellfafter which the cap is screwed back into place, thus holdingin place both packing 45 and springS. Although this means of packing is herein shown and described only as applied to three-way cocks, yet

it is evident that it may be applied to ordinary two-way cocks with equal advantage.

l. The combination of the shell, the plug, the packing 4, covering thejoint between the lower end ot' the plug and the shell, means for holding said packing in place, and the packing 45, surrounding the stem of the plug and held in place by a screw-cap, substantially as described.

2. The combination of the shell, the plug, the spring 3, heldin place by a screw-cap, and the packing 45, surrounding the stem of the plug, and also secured in place by a screw-cap, substantially as described.

3. The combination ot' the shell, the plug having the shoulders 1 and 2, the spring seated on shoulder 1, the cap 19, holding the spring in place, the packing45, surrounding the spindle 17, and the cap 21,holding the packing in place, all substantially as described.

In testimony whereofI have hereunto set my hand in the presence ot two subscribing witnesses.

DAVID MORRISON.
